The getting-started requirements now say a host needs 3 GB of RAM, 4 GB
recommended, and drop the advice to lower APP_MEMORY_LIMIT to 1g on a
2 GB host. The compose and .env example comments say the same.
At boot the app reads its cgroup memory limit (v2, then v1) and logs one
line when it is below MEMORY_FLOOR_MB. The support report adds the
container limit and a note below the floor, and Admin > System status
shows "below the supported floor" next to the existing low-heap flag.
The app keeps running either way.
